Einstein, Newton, and Pascal

The others agree, so Einstein begins counting. "One... Two... Three..."

Pascal runs off right away to find a place to hide.

But Newton merely takes out a piece of chalk and draws a mid-sized square. He finishes and steps into the square just as Einstein shouts, "Ready or not -- here I come!"

Einstein looks up and immediately spots Newton standing right in front of him. He says, "I found you, Newton!"

Newton replies, "No, you found one Newton per square meter -- You found Pascal!"
